ROLL FOR LOOM-TEM PLES.

SPECIFICATION forming part of Letters Patent No. 399,445, dated March 12, 1889.

Serial No. 288,106. (No model.)

T0 @ZZ whom it may concern.-

Be it known that I, BENJAMIN D. STEVENS, of Burlington, in the county of Chittenden, 1 State of Vermont, have invented a certain new and useful. Improvement in Rolls for ,l Loomflemples, of which the following a dei scription sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invent-ion appertains to make and use the same, reference being had to the accompai'iying drawings, forming part of this specification, in which- Figure l is an end elevation of my improved temple-roll; Fig. 2, a like view showing the opposite end of the roll; Fig. a vertical longitudinal section taken on the line .r m in Fig. l, and Fig. -LL a sectional view illustrating certain details of construction.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of loomtemple rolls which are provided with teeth or points; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a more effective and otherwise desirable device of this character than is now in ordinary use.

The nature and operation of the improve ment will be readily understood by all conversant with such matters from the following explanation.

ln the drawings, A represents the body of the roll, which is of thp ordinary form and construction, excepting as hereinafter described, and is adapted to be disposed in the temple in the usual manner. The body A is provided with a series of longitudinallyarranged equidistant grooves, e, preferably eight in number, the bottom of said grooves being inclined, as shown in Fig. 3, making them of greater depth at one end of the roll than they are at the opposite end, as illustrated by Figs. l and 2, respectively. Metallie plates m, adapted to enter said grooves, are provided on one edge with teeth or points t', the opposite edge of said plates being beveled longitudinally to conform tothe inclined bottoms of the grooves Each end of the plates mv is beveled, as shown at 'u in Fig. 2.

Each end of the body of the roll is reduced, forming an annular shoulder, (see Fig. 4,) and disposed on said reduced portions is a tight-fitting metallic ring, f.

In the use of my improvement the plates m are disposed in the grooves .2' and the rings f driven onto the reduced ends of the body A until they engage the beveled ends r of said plates and secure the same firmly in position in said grooves, said beveled ends r prevent ing the plates from being moved vertically in the grooves. By withdrawing a ring j' slightly on one end of the roll and forcing forward the ring on the opposite end thereof it will readily be seen that the plates can be moved longitudinally in the grooves, thereby adjusting the teeth thereon vertically in rela tion to the surface of the roll in a manner that will be readily understood by all conversant with such matters without a more ex plieit description. The temple is thus rendered much more effective in its operation, as the teeth may be readily adjusted to suit the character of the cloth which is being woven.

Having thus explained my invention, what I claim isl. A leoni-temple roll provided with aseries of longitudinal grooves having inclined bottoms and serrated plates disposed therein, an edge of each of said plates being inclined to conform to the bottoni of said grooves, substantially as set forth.

2. The combination of a roll having a series of grooves in its body provided with inclined bottoms, serrated plates disposed therein and having correspondin gly-inclined edges,wh ereby they may be adjusted vertically when moved longitudinally, and rings for securing said plates in posit-ionin said grooves, sub'- stantially as described.

3. A roll provided withv a series of longitudinal grooves having inclined bottoms, plates fitted to slide in id grooves, the outer edges of said plates being provided with teeth or point-s and the inner edges inclined to conform to the bottoms of said grooves, and ad junctive mechanism for detachably securing the plates in position, whereby the teeth or points may be adjusted vertically in relation ICO to the surface of the roll as the plates are duced ends and provided with grooves s, havmoved longitudinally, substantially as set ing longitudinally-inelined bottoms, in oomforth. bination with the serrated plates m, provided 4. The combination of a roll havin reduced with beveled ends if, and having' their inner 5 ends and provided with a series of longitudiedges inclined to conform to the bottoms of 2o nal grooves having inclined bottoms, plates said grooves, and the rings f, disposed on the provided with beveled ends and fitted to slide reduced ends of said body and adapted to enin said grooves, the outer edges Of said plates gage the ends fr of said plates and secure the being serrated and the inner edges inclined saine in position in said grooves, substantiallyT 1o to conform 'to the bottoms of the grooves, and as described.
